This isn't the response you're looking for James, but my view on all things personal data (per my previous contributions) is, I think, quite different to yours. In fact, accepting that we're in the same community based undoubtedly on some shared values, it seems we stand in quite different parts of the tent.
I have offered the polemic here that ownership is a red herring. And its securitization is wholly unlike any fabric of a co-operative and civilized society I recognise or wish to help build. This may in part be a European .v. US thing, if I was to fall back on shoddy stereotypes – shoddy because I'm sure there are people here who would immediately render that statement void. Or it could be that the tantalizing possibilities beyond the shoehorning of 21st Century challenges into 20th Century frameworks remain under-explored and under-celebrated.
On a more upbeat note, I find the current US approach to personal data nothing short of abhorrent, and perhaps I should celebrate from afar any effort to transform it. The caveat would have to be however that such an effort as you describe here be merely interim, absent any path dependencies that disallow for brighter possibilities down the road.
